DM3 (New 2010 model) - FAN NOISE - Constantly Running LOUD

This is the first HP to use "Cool Sense" technology. Yes, it is cool but at the expense of FAN NOISE. The fan runs constantly even when Thermal Assistant is set to "Quietest." Just an open browser window at 0-10% cpu makes the fan run all the time! PLEASE READ my Notes below.
After monitoring the temps, the fan still needlessly runs on medium speed even after the temperatures drop (CoreTemp gives [core#0 28C & core#1 37C] at idle powersaver). Anyone can comment on the 9C difference?
I believe hp still need to tweak the "Thermal Assistant" fan controller or raise the temperature thresholds. PLEASE HELP - VERY ANNOYING PROBLEM
Note: Latest F.08 bios & Turned OFF "Fan Always On." Computer is NEW (no dust). Used on Tabletop. Used both powersaver mode & balanced.

Try doing a SMC AND PRAM reset by:
1. Turn off your iMac and unplug everything from it for 30 seconds.
2. Plug in the power cord, keyboard and mouse only.
3. Press the power button and immediately hold down the Option, Command, P & R keys until you hear the second gong then release the keys. Your machine will start up normally, then check for the issues you are having.

MAC Mini wont turn on but the fan is constantly running loudly.

Hey, I'm new to MAC's and apple etc, I mostly use PC's and such but had to get a MAC for work purposes. Up to now it has been great and I can see why they are brill machines but last night when it wasn't even switched on the fan started up and now I can't even turn the Mini on. The only way to stop the fan (which sounds like a hair dryer - the only way I can describe it) is to unplug it at the mains. I'm worried that someone is going to tell me its bust and will cost a small fortune to repair but hey I gotta know.
Thanks.
Also I have tried pressing down the button to restart it etc but it just doesn't respond.

I am also having the same problem.
I came home after a long business trip to find that my computer was unplugged by my wife. After plugging it back in, fan on high, and no LED light.
I was quoted 500-600 to get it fixed. I bought the darn thing for only $450.
SMC reset has absolutely no effect what so ever.

I have Mac Pro 2010 model and it's giving heavy fan noise,so run the Apple hardware test but it's showing the Error: 4SMC 1 40000000 please help me in this issue.

New Macbook Pro 15 inch heat on the left and back bottom. Also, Fan is constantly running although I am only using Safari and it is a month old machine

I have a new macbook pro about a month old. Have not used for anything but internet browsing it is a 15" machine, I can feel the heat from the left corner and back bottom. Also, the fan is constantly running. Is this something I can do to resolve.

Fans are supposed to run whenever the Mac is on. Default/minimun speed is 2000RPM.
How hot is hot? Mine is running the CPU cores at 45-50C, the Radeon GPU 35-40C when not engaged, the chassis sensors 30-38C. And current ambient temperature is 27C at my location. I currently have Safari, Mail, TextEdit and Temperature Monitor online.
If you want a quick check of what the Mac's hardware is up to, download & install the iStat Pro dashboard widget. If you want a detailed view of the 20 or so different temperature sensors on the thing, download & install Bresink's free Temperature Monitor. And if you want to see ALL the different sensors it has, purchase Bresink's Hardware Monitor.

Fan is constantly running

I have a MacBook Pro about 3 years old and all of a sudden it seems to be heating up and the fan is constantly running to cool it!
Anyone have this problem? Suggestions on what to do?
Thanks.

Shut down your computer with  > Shut Down. Start it up. Does it still happen?
Edit: Shootist has a good suggestion about cleaning out dust. Use a vacuum cleaner with a brush near the vents in back to draw it out, vs. blowing dust back into the computer where it will only cause more problems.

Brand new macbook pro retina - fan noise when running hola?

Hi everyone, I need some help here please!
I have a brand new macbook pro retina 13 - just bought in January this year - and have had no problems so far apart from the wifi dropping occassionally.
So I just downloaded hola unblocker for firefox but whenever I stream anything using it on netflix my fan starts whirring so loudly - it's never even made a noise before! and I can feel the base of the mac getting hotter. So I've closed hola/firefox and it stops after a minute or so. I've tried a few times again with the same problem.
I'm just using it to watch US netflix so probably not technically legal anyway.... but other friends manage it no bother - do mac's just know I'm doing something wrong? haha
Thanks for any advice.

Try running Activity Monitor (in the Utilities folder). Click the Energy button at the top and then stream a video. Watch the Energy Impact.
I suspect what you'll see is that your rMBP is doing a lot of work while you're streaming the video, and that makes it get hot. The fan struggles to dissipate the resulting heat in order to prevent damage and makes noise in the process.
It may also have a guilty conscience.

My Macbook Pro 2010 model is hanging constantly. Please Help

Well, i have Macbook pro 2010 model. Since yesterday it is hanging and has becoming frealing slow. I have cleared the memory, deleted unnecessary apps & files. Still no improvement. Please help!!

Why are the fans on my macbook constantly running loudly

The fans on my macbook are running loudly and my computer is running very slowly.
Does anyone know a solution to this?

Either the cpu is cycling doing some intensive work (see Activity Monitor) or the SMC needs resetting.

You can also install an app to monitor temperature and speed eg SMC Fan Control.

Can't use FaceTime because fan noise is so loud

I have my Macbook Pro connected to a Thunderbolt display and when I'm using them, I have the Macbook lid closed and I tuck it under the display. However, for a few weeks now, when I try to use FaceTime, the fan kicks on so loudly that the person I'm talking to can't hear me. This setup used to work just fine, now it doesn't.
It's not just FaceTime that causes the fan to kick in, it's really when I play video of any kind. It requires a lot of processing as we all know, but I'd like to figure out why it used to not be a problem but now it is and I'm just not sure where to start. I have plenty of ventilation around my computer and I've closed all other running apps but it's never made a bit of difference.
I've searched the forums here a lot and found a lot about killing processes and such, but that seems to be addressing siutations in which the fan runs a lot for no apparent reason. For me, it's very clear that it happens when I do anything involving video.
I saw a suggestion to reset the SMC which I could certainly do, but it seems like that shouldn't be the first thing I try.
Can anybody recommend anything else before I try something like that?
Thanks

That's correct. It is banned by law in KSA, UAE and Qatar.

Fan constantly running loud - iStat reporting 0 rpm

Hi guys,
hope somebody can help me, my iMac suddenly started to make a very loud noise, the fans are spinning at high RPM!
I already tried to reset the SMC, unplugged my Mac for a couple of hours, plugged it in while pressing the power button - unfortunately nothing helped. When starting while holding the power button, it gets even noisier, therefore i expect only one of the fans is running at full or near full speed constantly.
I now tried to install some hardware monitors to check on temperature/fan speed. iStat nano is reporting low temperatures, but the strange thing is that it gives 0 rpm for the CPU fan, even though its clearly running at high revs...
I don't have Apple care and my iMac 24" is now roughly two years old. Any help is highly appreciated!
thanks,
A

Hi is it normal for a brand new imac CPU usage be constantly running at around 78% when nothing is running ?

Hi I bought a new imac for Christmas, set it all up and installed all updates including maverick os. At first the imac ran very slow so I left it to sort any updates out but keep getting an error message when I boot up, say unexpected restart etc.
Also the activity monitor shows the CPU is constantly at around 78% with nothing being open or used.
Is this normal ?
To be honest I'm not impressed at how sluggish the mac is.
Shaun

hi john,
apple care advised to take to a local store to be checked. when i arrived at the apple store i explained that the fans were on full belt and the cpu load and they just gave me a new one :-)
set it up instore this time and its miles better!

Brand new Macbook Pro -Fans on constantly at 6000 rpm. Very Noisy. Broken ?

Just bought a macbook pro today. The fans on it are constantly on ... all of them, spinning at 6000rpm no matter what the machine is doing. It sounds like a hurricane. I have tried to reset the SMC (no effect), update the firmware and EFI (refuses .. saying this update is not required), reset the pram (no effect) and resinstall OSX (no effect). The temp of the machine is only 34 degrees C (no doubt due to the fans being on constantly).
Its like this on battery / AC / and even on better energy saving settings !
Whilst the machine works, it is unusable. It sounds like a vacuum cleaner.
There are utilities out there (smcfancontrol) that let you set the minimum speed for your fans but not the maximum speed... ! Typical. !
Any suggestions... otherwise I will be returning this machine to a John Lewis branch tomorrow and asking for a refund (faulty machine). I suspect the thermo monitor is borked.
??? Thanks for any suggestions

I have exactly the same problem - right down to the last of your words!
I have had discussions with Apple Care but, sadly for me, I will have to have them look at it in my local apple store and I have no idea how long it will take.
All I can say is that the noise is terrible - when you shut it down its like lovely peace and quiet! Imagine me in the library at Uni - I sound like the cleaning person!
Good luck with your return and I will see what happens once I can actually get hold of someone from Apple Store!

CPU Fan speed constantly running at 5000-5500rpms!

I have Cool-N-Quiet enabled in BIOS, AMD64 driver loaded and Power Management set to Minimal.
I know the Cool-n-Quiet is working because when I load CoreCenter it shows the CPU speed at 801Mhz.
However, my CPU Fan speed is always around 5000-5500rpms! My CPU temp is normally around 42C.
I can lower the fan speed manually to 2000rpm or so but as soon as I turn Cool-n-Quiet back on the fan speed jumps to 5000-5500.
Anyone know what could be causing this and how to fix it?

Fan is always running loudly on Macbook Pro

I've had my Macbook Pro for just over three years now, and I haven't had a problem with the fan before now. A month or so ago I started noticing the fan was always on a constant hum, not so much that it was a problem, but just present. I figured I was just doing too much with it, even though I don't use much other than word, safari, and iTunes. Over the last couple weeks, however, I've noticed the hum just getting louder constantly. I've tried restarting the computer several times, and I can usually go about 10 minutes after that without the fan being loud, sometimes less if I try to play a video.
At this point there are times when it literally sounds like there's a motorcycle in my laptop, and I can feel a vibration when I type. However, I got a monitoring app and it says the temperature and fan speed are both at a normal temperature. I'm not sure what this means for my laptop, and I really want to fix this problem.
Any thoughts?

First try a SMC reset:
http://support.apple.com/kb/ht3964
If there is no change, open the MBP and look inside. Your MBP may very well have dirt and debris that needs to be cleaned out.
If that is not the case, run an Apple Hardware Test:
http://support.apple.com/kb/ht1509
Note that an error free AHT is NOT definitive.
The last resort is an appointment at an Apple store genius bar for a free evaluation.
Ciao.
